Abstract

The invention provides a vertical ellipse-like full-section tunnel shield tunneling machine which comprises a cutter head and a shield body; an overbreak cutter adjusting mechanism is installed on the cutter head; a segment erector is movably installed in the shield body; and a spiral conveyor penetrates through the segment erector. According to the vertical ellipse-like full-section tunnel shield tunneling machine, a vertical ellipse-like full-section adjusting system is formed by the overbreak cutter adjusting mechanism, a height adjusting mechanism and an opening integrally, one-time excavation, temporary supporting and segment splicing forming of a long-distance vertical ellipse-like section tunnel can be achieved, the construction procedures are reduced, the construction cost is saved, and a safe, efficient and reliable solution is provided for construction of the vertical ellipse-like section tunnel.

Description

technical field [0001] The invention relates to the technical field of shield machines, in particular to a vertical type elliptical full-section tunnel shield machine. Background technique [0002] Traditional shield tunnels are generally circular, but the utilization rate of circular tunnels is relatively low; in some special cases, due to the advantages of vertical elliptical cross-section tunnels with good mechanical structure, good ventilation, and high space utilization , this type of tunnel needs to be built; since the section of the tunnel is non-circular, there are many difficulties in excavating the muck and assembling the segment with the conventional shield machine, so the vertical elliptical tunnel generally adopts the mining method, underground excavation Construction methods, such as manual or mechanical excavation, transport the muck to the outside of the tunnel, and then make steel arches, bolt bolts and other processes to perform primary support and secondar...
